To all whom it may 0on0 lie it lzncm'n i zen oi the U1. cage, in tire nouns Illinois, have Z I l'ul Improvements in Deep and I do hereby declare lilo following to be e full, elem; and exact descrip bion of. the invention, such on wil enable others skilled in the art to which it npperteins 53o make and use the some.

My invention relates to pumps and more particularly to pumps suitable for raising Water from deep Wells.

One object of my invention is to provide a simple and compact pump of such shape as to be readily lowered into the bore of a Well, and one that may readily be actuated by vertical shaft.

Another object is tonro'vids simple means for supporting both or member of the pump and the secii the shaft so as to relieve the lower end of Lhe from the strain of their weight.

Furl-her objects are to provide construction so designed as o f stream of water into the i the pump, and co provide a checking a return flow oi he W3 pump chamber in case s'ropivin slowing of time animating: poriions of pump.

couplings 19 to addition 11 tubesections ll ,of such number an?v length as may be re quizecl for the depth of the Well, the lowest the sections being secured to the upper end iii of a pump chamber 13. Mounted Within the said end 12 another brill role 14 supporting 2L collar 15 secured to the lower end 16 of the said vertical shaft. interposed between the said lower end 16 and the upper end 7 are intermediate shaft sections being secured to each other by slip joints or tenons 18, which tenons afiord interlocking formations for non-rotamloly coupling the adjacent shaft sections while permitting a relative longitudinal motion of said sections to compensate for the expan ohm or contraction due to temperature changes.

Secured, to the lowest section l6 of the vertical shaft within the said pump chamber 1.3 is a propeller member li having a pluralty of blades 20 disposed in substantially l spiral formation about time axis of: the said shaft. The lower edge rtlons 21 of the old propeller blades are nreierably curred in concave formation. corresponding to the convex curvature of the upper end of a suclion lube secured to the bottom of the pump elm/ oer 13. The said suction iube carries its lower end ovv screen 23 ancl'has counted Within it a spider 24 supporting a pivoted screw 25 engaging a conical recess in the extreme lower end of rotating shaft, whereby the said slio'ft be held accurately centered with respect to the pump chamber. Howevergthe nrliustment of the supporting flanges 6 15 with respect to the shaft is nrer'erablv such {is-to relieve the screw 25 of supporting the Weight of the shaft and the propeller, so that the said pointed screw need onlvto act as centralizing' griide means for the rotating portion of my uinn. 1

'oiluan'd to feed the same'into the tubular bore 31 of the shaft through a transverse perforation 32 alining with the said oil chamber 30. Upposite the bearing portions 33 of each of the saidc'ouplings 10, and the shaft dS provided with 'ations 34 permitting the oil inner tube 31 to'floW-tofthe transverse. perfoi from the said said bearings and ball races. The shaft l likewise a transverse perforation 35 alining with an oil chamber 36 disposed in the pinup chamber 13 abovethe'propeller member of my pump and-from which the to the adjacent bearings of the shaft, propellermeniber and pump chamber. I i It will be ma netron theabove'des'crip tion that the pump (115/ rnx invention may esii'ed depth by i simply providing a suilici'en't number ofthe extension tubes fend interm cdiary shaft pieces, and that by providing a corresponding numbcr'of the ball races and flanges mounted upon the respective portions of the shaft, the of the pump may be relieved of undue strain and friction. it will also be evident that by curving the lower ends 21'ofthe -pro- I J' peilei blades, one s id blades can operate-. with a minimum of clearance within.v the pump chamber, thereby pern1itting th e. stream of Water to be efficiently directedpipe 29. In case the speed of operation of the pump is reduced,.or'thep'umpis entirely stopped, case the flow of water through 29 meets an unexpected. resistance,

The length of the screw, pitch of the blades, etc, may obviously be increased or diminished without departingfrom the in lower or operating member vention. And in place of one screw or: propeller a plurality thereof may be mountedone above the other in the. pump chamber as will be apparent. To insure a continuity of the oil-supplying duct or here of the jointed vertical shaft, the adjacent ends -.of the sections may be counterbored and fitted with tubes 38 connecting thesaid ends, as shown in Fig. l, the said tubes being slidable with respect to at least one of said shaft section's;

I claimas my invention:

1-. In a pump, .the combination with a plurality of verticalshaft sections insubstantially axial -aline'ment with each other, ofa tube housing said sections, and'separatebearings carried by the tube and independently carrying said sections respectively; the conjacent ends with non-rotatably 7 said formations'slida mit relative motion longitudinally of th 'fordiffe'rences in contraction of th ti'ons. i 2. Ina pump, the combination with a plus rality-ofvertical and liollhw shaft sections in 'substantially axial alinementvrith each other, of a tube housin interlocking formations for bly interfitting to perof the coupled sections e latter to compensate the relative expansion and e tube and the shaft secsecutive sections being equipped attheir ad- I coupling said sections," ixthe g said sections, and

scparate bearings carried by the 'tubeand independently carrying said sections re -spectively; the consecutive sections being equipped at their adjacent ends with interjlocliinggformationsfor non-rotatably coupling said sections,

slidably interfitting to permit relative mo tion of the coupled sections longitudinally of the latter, the pores ofthe shaft sections being enlarged at latter; and oil tubes connecting the the said formations the coupled ends of the coupled i ends of the shaft sections, each. of said tubes being slidablewith respect to at least on'e of 1100 the shaft sections coupled thereby and housedat its ends by the said shaft sections.
